Description

The present invention relates to a liquid treatment system for suctioning liquid, which is suitably used for muddy water treatment during flood disasters.

In recent years, flood damage caused by sudden heavy rains such as torrential rain or river flooding caused by large typhoons has been increasing. When rivers flood, large amounts of muddy water rush into residential areas, and the treatment of this muddy water has become a social issue. Even after the river water level drops and the water recedes, muddy water containing a large amount of water remains in the flooded areas. Particularly in flooded areas in residential areas, the removal of muddy water after the water has receded is often done manually by local residents and volunteers using shovels and other tools. It is difficult to scoop up muddy water that contains a lot of water immediately after a flood with a shovel. Therefore, the workability of collecting muddy water into sandbags or the like is poor and efficiency is low. Additionally, the sandbags that collect muddy water are heavy and require hard labor to handle.

As described above, manual muddy water removal work requires long hours of hard labor, which places a heavy burden on disaster victims.

Additionally, over time, the water in the muddy water loses its moisture and becomes dry to some extent. However, when shoveling, dried mud is scattered. This can be alleviated by spraying the dry mud with water, such as tap water. However, in many cases, water and/or power outages occur in disaster-stricken areas. Generally, power outages are quickly restored, but water and sewage outages require a considerable amount of time to be restored. Since tap water cannot be used until the water outage is restored, workers are forced to shovel for long periods of time in difficult conditions.

In addition, in order to recover from flooding above or below the floor of a house, it is necessary to remove muddy water that has accumulated under the floor. Currently, the work of removing muddy water from under the floor requires workers to crawl under the floor and do the work manually, which is extremely hard work. Once the muddy water under the floor dries, the job becomes even more difficult.

On the other hand, it is conceivable to use mechanical means such as suction devices to remove muddy water, but large-scale equipment poses a problem of mobility. For example, when removing muddy water using a large work vehicle, it may be difficult to access the disaster area. After the disaster, the main roads are covered with mud and garbage, making it impossible for large work vehicles to reach residential areas. In order to remove muddy water from residential areas using large work vehicles, it is first necessary to remove muddy water from main roads and roads surrounding residential areas so that the large vehicles can move to residential areas.

The configuration of existing suction devices is insufficient in terms of workability, work efficiency, mobility, etc. to deal with flood damage. For example, Patent Document 1 describes a recovery device that uses compressed air to suck up solids and liquids. In this device, the collected liquid and solid are separated from each other through a wire mesh, and the separated liquid is discharged from the device by gravity. Patent Document 1 contemplates the recovery of machining cutting fluid containing chips. A specific method for taking out the separated solid from the apparatus is not described in Patent Document 1.

Patent Document 2 describes an apparatus for dewatering sludge materials such as sludge generated during civil engineering or construction work. Specifically, Patent Document 2 describes an apparatus that separates water by vacuum suction from a muddy substance placed on a mesh bag inside a cylinder and a filter cloth. The separated water is discharged to the sewer. After separation, the mud is lifted up along with the cylinder or from the cylinder together with the net bag and filter cloth.

Moreover, Patent Document 3 describes a vacuum cleaner for construction sites. Specifically, Patent Document 3 describes an apparatus that sucks muddy water into a mesh bag and then separates the muddy water into muddy soil and water. This equipment requires a dedicated submersible pump and vacuum blower to discharge the water after separation. The separated mud is taken out of the device along with the mesh bag.

The muddy water removal work described above requires the removal of a large amount of muddy water. However, the configuration of the existing suction device leaves room for improvement in order to continuously suck muddy water during muddy water removal work. For example, in the device described in Patent Document 1, the separated liquid is discharged from the device by gravity, and there are restrictions on the installation of a container or the method for recovering the liquid. Furthermore, Patent Document 2 does not disclose a specific method for discharging separated water into sewage. Further, in Patent Document 3, a submersible drainage pump is provided in a pump tank, and in order to continuously suck and discharge water, a driving source is required for each of the suction device and the submersible pump. Furthermore, since the submersible pump is placed inside the tank, the device becomes large. These challenges also exist when collecting liquids such as rainwater that do not contain much solid matter such as mud.

In view of at least some of the above circumstances, one purpose of the present application is to propose a compact liquid processing system that can continuously suck liquid.

According to one embodiment, a liquid handling system for aspirating and collecting liquid is proposed, the liquid handling system comprising a vacuum generating module and a negative pressure generated by the vacuum generating module connected to the vacuum generating module. a vacuum tank into which liquid is sucked by the vacuum tank; a first opening extending from the vacuum generating module into the vacuum tank and opening into the vacuum tank at a first position; and a second position higher than the first position. and a second opening opening into the vacuum tank.

<First embodiment>
Embodiments of the present invention will be described below with reference to the drawings. Note that the following description is merely an example, and is not intended to limit the technical scope of the present invention to the following embodiments. Further, in the drawings, the same or corresponding components are given the same reference numerals and redundant explanations will be omitted.

FIG. 1 is a diagram showing an overall outline of a muddy water treatment system (hereinafter referred to as system) 100 in one embodiment of the present invention. System 100 represents one embodiment of a liquid handling system. The system 100 can be used to perform muddy water removal work in areas affected by flooding. As shown in FIG. 1, the system 100 includes a vacuum generation module 50 as a negative pressure source, a vacuum tank 40, a recovery tank 20, a drainage tank 70, and an injection device 80.

The vacuum generation module 50 is configured to generate negative pressure within the vacuum tank 40. In this embodiment, the vacuum generation module 50 includes a compressor 106 and a diffuser 54, and generates negative pressure in the vacuum tank 40 by discharging compressed fluid (for example, air) from the compressor 106 from a nozzle to the diffuser 54. An ejector method is adopted. However, the vacuum generation module 50 is not limited to the ejector type, and a vacuum pump or the like may be used.

The vacuum tank 40 is connected to a vacuum generation module 50 to generate negative pressure therein. The recovery tank 20 is connected to the vacuum tank 40 via a connecting pipe 104, and the negative pressure inside the vacuum tank 40 can be applied to the inside of the recovery tank 20 via the connecting pipe 104. A suction pipe 102 is connected to the recovery tank 20, and muddy water is sucked through the suction port of the suction pipe 102. The recovery tank 20 is configured to recover mud (solid matter) contained in the sucked muddy water. The muddy water from which mud has been removed is sucked from the recovery tank 20 into the vacuum tank 40 via the connecting pipe 104. For example, the connecting pipe 104 is preferably connected to the lower side (lower surface or lower side surface) of the recovery tank 20 and the upper side (upper surface or upper side surface) of the vacuum tank 40.

An air/water intake pipe 60 is provided inside the vacuum tank 40 . The air suction pipe 60 is connected to the suction port of the vacuum generation module 50 . The intake water intake pipe 60 will be described in detail later. The outlet of the vacuum generation module 50 is connected to the drain tank 70 via an exhaust drain pipe 108. In addition, in this embodiment, when negative pressure is generated by the vacuum generation module 50, the insides of the vacuum tank 40 and the recovery tank 20 become negative pressure. On the other hand, the drain tank 70 is open to the outside, and the inside thereof is at about the outside pressure regardless of the operation of the vacuum generation module 50. Note that the system 100 may not include the drain tank 70, and the exhaust drain pipe 108 may be connected to a sewer or the like.

The injection device 80 is configured to be able to inject the liquid stored in the drainage tank 70 from an injection port 80a. Preferably, the injector 80 is configured to be able to be injected/deactivated by the user of the system 100. As a result, the user can, for example, direct the injection port 80a toward the place where muddy water removal work is to be performed and spray the liquid to remove hardened muddy soil or collect muddy water, thereby improving the work efficiency of muddy water removal. can. For example, the injection device 80 is configured to use the power generated by the vacuum generation module 50 to inject the liquid. In this embodiment, the injection device 80 is configured to be able to inject liquid from the injection port 80a using compressed fluid by the compressor 106. However, the system 100 is not limited to such an example, and the system 100 may further include a power source for the injection device 80. Additionally, the system 100 may not include the injection device 80.

In such a system 100, muddy water is sucked into the recovery tank 20 from the suction port of the suction pipe 102 using negative pressure generated by the vacuum generation module 50. In the recovery tank 20, mud contained in the muddy water is separated and recovered, and water and fine mud are sucked into the vacuum tank 40 through the connecting pipe 104. The liquid stored in the vacuum tank 40 is discharged to the drain tank 70 through the air intake pipe 60, the vacuum generation module 50, and the exhaust drain pipe 108. Such a system 100 can save labor in muddy water removal work. Furthermore, muddy water removal work can be carried out continuously over a long period of time.

Additionally, the system 100 has excellent maneuverability. For example, the recovery tank 20, the vacuum tank 40, and the drainage tank 70 can have a relatively compact configuration, and can be relatively easily transported to the disaster area and installed at the site. Further, the recovery tank 20, the vacuum tank 40, and the drainage tank 70 may be transported by separate small vehicles, if necessary. This allows access to the disaster area relatively quickly.

FIG. 2 is a schematic diagram showing a part of the configuration of the muddy water treatment system shown in FIG. 1 in more detail. In FIG. 2, the vacuum generation module 50, the vacuum tank 40, and the air/water intake pipe 60 are mainly shown.

In the example shown in FIG. 2, the vacuum generation module 50 employs an ejector type. As illustrated, the vacuum generation module 50 includes a compressor 106, a nozzle 52 to which compressed fluid from the compressor 106 is supplied, and a diffuser 54. As an example, nozzle 52 and diffuser 54 are attached to the top of vacuum tank 40. However, the present invention is not limited to this example, and the nozzle 52 and diffuser 54 may be attached to the side surface of the vacuum tank 40, for example. In the vacuum generation module 50, negative pressure can be generated by causing compressed fluid from the compressor 106 to flow into the diffuser 54 through the nozzle 52.

The air suction pipe 60 is connected to the suction port (lower side in FIG. 2) of the vacuum generation module 50 and extends into the vacuum tank 40. The air/water intake pipe 60 is made of a highly rigid material such as metal or resin, for example. In this embodiment, the upper end of the air intake pipe 60 is connected to the diffuser 54 and the upper surface of the vacuum tank 40, and the lower end is located within the vacuum tank 40. However, the air intake pipe 60 may be formed integrally with the vacuum generation module 50, such as integrally formed with the diffuser 54. Alternatively, the air/water intake pipe 60 may be configured integrally with the vacuum tank 40.

As shown in FIG. 2, the air/water intake pipe 60 has a water intake port (first opening) 62 and an intake port (second opening) 64 that open into the vacuum tank 40. The water intake port 62 is formed at a relatively low first position within the vacuum tank 40, and the air intake port 64 is formed at a relatively high second position within the vacuum tank 40. That is, the intake port 64 is formed at a higher position than the water intake port 62. As an example, it is preferable that the water intake port 62 be formed at a position lower than the center of the vacuum tank 40, and the air intake port 64 be formed at a position lower than the center of the vacuum tank 40.

Further, in the example shown in FIG. 2, the intake port 64 has a smaller size than the water intake port 62. Here, the intake port 64 and the water intake port 62 are circular openings as an example, but may have any shape such as a polygon. In this embodiment, "dimension" means diameter or radius when the aperture is circular. Furthermore, when the opening is polygonal, "dimension" means the length of one side or the minimum opening width passing through the center. Alternatively, the dimensions of the aperture may be defined by the diameter of a circle having an area equivalent to the aperture area. The dimensions of the water intake port 62 are:
For example, it can be about 1.2 times, 1.5 times, or twice the size of the intake port 64.

Furthermore, in the example shown in FIG. 2, the water intake port 62 is formed at the lower end of the air intake pipe 60 and opens vertically downward. Further, the air intake port 64 is formed by connecting an elbow pipe to the side surface of the air/water intake pipe 60, and opens vertically upward. Although not limited to this, the water intake port 62 is preferably opened horizontally or vertically downward rather than horizontally, and the air intake port 64 is preferably opened horizontally or vertically upwards rather than horizontally. .

The operation of the system 100 equipped with such an air/water intake pipe 60 will be explained. When the vacuum generation module 50 operates, when there is little muddy water in the vacuum tank 40, air in the vacuum tank 40 is sucked in through the water intake port 62 and the intake port 64, and the air is discharged into the drain tank 70 through the exhaust drain pipe 108. The negative pressure within the vacuum tank 40 acts on the recovery tank 20 and the suction pipe 102 via the connecting pipe 104. Thereby, the user can suck muddy water into the recovery tank 20 and the vacuum tank 40 through the suction pipe 102. When the water level of the muddy water in the vacuum tank 40 reaches the water intake port 62 of the air intake pipe 60, the muddy water is sucked in from the water intake port 62, and the air in the vacuum tank 40 is sucked in from the intake port 64, and the air is discharged through the exhaust drain pipe 108. And muddy water is discharged into the drainage tank 70. By providing the air intake water suction pipe 60 in this way, muddy water (liquid) sucked into the vacuum tank 40 can be drained into the drainage tank 70 through the air intake water intake pipe 60. Note that since the drain tank 70 is open to the outside, when the drain tank 70 becomes full, the drain tank 70 can be easily replaced, and the muddy water (liquid) sucked into the vacuum tank 40 can be removed. Can be drained continuously.

<Second embodiment>
3 to 5 are diagrams schematically showing a configuration overview of a muddy water treatment system 100A according to the second embodiment. The muddy water treatment system 100A (hereinafter also referred to as "system 100A") of the second embodiment is generally the same as the muddy water treatment system 100 described above, and the same components are given the same reference numerals and redundant explanations will be omitted. do. Note that in FIGS. 3 to 5, illustration of the drainage tank 70 is omitted. Two connecting pipes (first connecting pipe, second connecting pipe) 104A, 104B that can be opened and closed by water flow valves 105A, 105B are attached to the vacuum tank 40A of the muddy water treatment system 100A of the second embodiment. The vacuum tank 40A can be connected to two recovery tanks (a first recovery tank and a second recovery tank) 20A and 20B. Suction pipes 102A and 102B are attached to the two recovery tanks 20A and 20B, respectively. Furthermore, the air intake pipe 60 of the second embodiment is provided with a vent valve 65 that can open and close the intake port (second opening) 64 . The water flow valves 105A, 105B and the ventilation valve 65 are configured to be operable by the user of the system 100A. Note that in the examples shown in FIGS. 3 to 5, the vent valve 65 is provided inside the vacuum tank 40A, but the invention is not limited to this example, and the vent valve 65 may be provided outside the vacuum tank 40A. Good too. In this case, the intake water intake pipe 60 has a branch pipe (not shown) that is connected to the main body of the intake water intake pipe 60 and passes through the outside of the vacuum tank 40A to define an intake port 64 within the vacuum tank 40A. The vent valve 65 may be provided in the branch pipe. The water flow valves 105A, 105B and the ventilation valve 65 may be any known on-off valve, and may be a manual on-off valve, an electric on-off valve, or the like.

In the system 100A of the second embodiment, muddy water removal work can be performed with switching between the two recovery tanks 20A and 20B. With reference to FIGS. 3 to 5, processing when switching the recovery tanks 20A and 20B in the system 100A will be described. Here, in FIGS. 3 to 5, when the flow path is closed by the water flow valves 105A, 105B and the ventilation valve 65, the valves are shown in black, and when the flow path is open, the valves are shown in white. It is shown in

As shown in FIG. 3, the system 100A utilizes the recovery tank 20A connected to one connecting pipe 104A by opening one connecting pipe 104A and closing the other connecting pipe 104B connected to the vacuum tank 40A. muddy water removal work. As a result, solid matter (such as mud) contained in the muddy water is collected in the collection tank 20A, and the muddy water is sucked into the vacuum tank 40A. Further, at this time, by keeping the vent valve 65 open, the muddy water and air in the vacuum tank 40A are sent to the drainage tank 70 (not shown in FIG. 3) through the air intake pipe 60 as described above. Note that the lower the water level of the muddy water in the vacuum tank 40A, the more gas is discharged through the suction pipe 60, and the higher the water level of the muddy water in the vacuum tank 40A, the more liquid is discharged through the suction pipe 60.

Subsequently, as shown in FIG. 4, when the amount of mud in the recovery tank 20A increases due to muddy water removal work and the recovery tanks 20A and 20B are to be switched, the user closes the vent valve 65 of the air intake pipe 60. . This prevents air from being sucked in through the intake port 64, and the muddy water in the vacuum tank 40A can be positively discharged to the drainage tank 70. Note that the recovery tank 20A is provided with an exhaust valve (not shown) that communicates the inside and outside of the recovery tank 20A, and when draining the muddy water in the vacuum tank 40A, the exhaust valve of the recovery tank 20A is opened. It can also be used as a thing.

Then, as shown in FIG. 5, by closing the connecting pipe 104A and opening the connecting pipe 104B, the recovery tank communicating with the vacuum tank 40A can be switched from the recovery tank 20A to the recovery tank 20B. The fluid connection between the recovery tank 20A and the vacuum tank 40A is disconnected, and the user can easily dispose of the mud accumulated in the recovery tank 20A by taking it outside. Further, a recovery tank 20B is fluidly connected to the vacuum tank 40A, and muddy water removal work can be continuously performed using the recovery tank 20B. Thereby, similar to the muddy water removal work using the collection tank 20A, the solid matter contained in the muddy water is collected in the collection tank 20B. Also, at this time, by opening the vent valve 65, muddy water and air in the vacuum tank 40A are drained into the drain tank 70 through the air intake pipe 60.

As explained above, the vacuum tank 40A of the second embodiment is connected to the two recovery tanks 20A, 20B via the two connecting pipes 104A, 104B, and while switching between the two recovery tanks 20A, 20B, Can perform muddy water removal work. Note that, as described above, each of the recovery tanks 20A and 20B may be provided with an exhaust valve that communicates the inside and outside of the recovery tanks 20A and 20B. Further, the timing of opening and closing the water flow valves 105A, 105B and the ventilation valve 65 is not limited to the above-described example, and may be appropriately determined by the user according to the usage state of the system 100A.

<Third embodiment>
FIG. 6 is a diagram schematically showing a configuration overview of a liquid processing system 100B according to the third embodiment. The liquid treatment system 100B (hereinafter also referred to as "system 100B") of the third embodiment is generally the same as the muddy water treatment system 100 described above, and the same configurations are given the same reference numerals and redundant explanations will be omitted. do. The vacuum tank 40B of the system 100B is connected to the suction pipe 102 instead of being connected to the recovery tank 20 via the connecting pipe 104. That is, system 100B is different from system 100 described above and does not include recovery tank 20.

In system 100B, liquid drawn from suction tube 102 is sucked directly into vacuum tank 40. Further, the vacuum tank 40 is provided with an air intake pipe 60 as in the above-described embodiment, and the liquid sucked into the vacuum tank 40 can be discharged to the drainage tank 70 through the air intake pipe 60. . The system 100B of the third embodiment can be suitably used, for example, when removing a liquid that does not contain many solid substances, such as rainwater, or a liquid that does not contain any solid substances at all.

<Modified example>
FIG. 7 is a diagram showing a configuration corresponding to FIG. 2 of a muddy water treatment system according to a modified example. As shown in FIG. 7 , the intake port 64 (intake port 64A) of the intake/water intake pipe 60 may be an opening formed in the side surface of the main body of the intake/water intake pipe 60 . Further, the intake port 64 (intake port 64B) of the air/water intake pipe 60 may be formed by a connecting pipe extending from a position lower than the center of the vacuum tank 40 to a position higher than the center. Further, the air/water intake pipe 60 may have a plurality of water intake ports 62 or may have a plurality of intake ports 64.

The vacuum tank 40 in the mud treatment system of the fourth embodiment is configured so that water can be discharged from a drain pipe 110 connected to the bottom of the vacuum tank 40 in addition to the air intake pipe 60. A diffuser 154 is provided in the drain pipe 110, and a nozzle 152 to which compressed fluid is supplied is arranged inside the diffuser 154. The nozzle 152 is connected to the compressor 106 that supplies compressed fluid, and is configured to flow the compressed fluid into the diffuser 154 in a direction away from the vacuum tank 40. In other words, the suction port of the diffuser 154 is connected to the bottom of the vacuum tank 40. In addition, in the example shown in FIG. 8, the compressor 106 in the vacuum generation module 50 is used as the compressor 106, but the present invention is not limited to such an example. Further, the compressor 106 in the vacuum generation module 50 may be configured to select only one of the nozzle 52 and the nozzle 152 and supply the compressed fluid, or compress the fluid to both the nozzle 52 and the nozzle 152 at once. It may be configured to supply fluid. In the vacuum tank 40 of the fourth embodiment, the muddy water (liquid) sucked into the vacuum tank 40 can be discharged through the drain pipe 110 by allowing compressed fluid to flow into the diffuser 154 from the nozzle 152. In this way, in the mud treatment system of the fourth embodiment, the liquid sucked into the vacuum tank 40 can be discharged to the outside from each of the air intake pipe 60 and the drain pipe 110, and the liquid can be continuously discharged more preferably. It becomes possible to aspirate the Note that the drain pipe 110 is preferably connected to the drain tank 70 together with the exhaust drain pipe 108. The drain pipe 110 may be connected to and integrated with the exhaust drain pipe 108, or may be connected to the drain tank 70 separately from the exhaust drain pipe 108. A flow regulating valve (not shown) may be provided in the compressed air pipe from the compressor to the nozzle 152. Further, the drain pipe 110 may be provided with a manual or electric water stop valve (not shown). Furthermore, in the example shown in FIG. 8, the drain pipe 110 is connected to the vacuum tank 40 directly below the water intake port 62 of the air intake pipe 60. However, the drain pipe 110 is not limited to this example, and the drain pipe 110 may be connected to the vacuum tank 40 at a position different from the water intake port 62 when viewed in the vertical direction.

FIG. 9 is a diagram showing another example of a configuration corresponding to FIG. 2 of the mud treatment system of the fourth embodiment. In the example shown in FIG. 8, the drain pipe 110 (diffuser 154) is attached to the bottom of the vacuum tank 40. Instead, in the example shown in FIG. 9, the drain pipe 110 (diffuser 154) is attached to the side (side surface) of the vacuum tank 40. Even in such an example, the same function as the example shown in FIG. 8 can be achieved. Note that when the drain pipe 110 is attached to the side of the vacuum tank 40, it is preferably attached to the lower end of the vacuum tank 40 or near the lower end.
